MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 246,617, dated September 6, 1881, Application filed February 2 1881. (No model.)

To all whom it may concern Be it known that I, EMANUEL W. KITCHEN, a citizen of the United States, residing at Garversville, in the county of Bucks and State of thereon, which form a part of this specification.

My invention relates to improvements in milk-coolers; and it consists in a certain novel construction and arrangementof parts, hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view, partly in section, of my complete device, and Fig. 2 is a longitudinal section of the water-cooler.

A represents the milk-cooling vessel, which is hinged or pivoted at a to a table or support, 13, to admit of said vessel Abeing readily tilted back whenever it may be desired to cleanse the same, which may be readily accomplished by pouring water through the front ends of the pipesb or passinga swab therethrough. These pipes b' extend longitudinally from the front and incline upwardly to near the latter end of the vessel A, and receive the milk which is poured in at the rear end of the vessel, and convey it to the front of said vessel, where it is discharged into the extended portion a, passing from thence through the orifice d to the spout c, from whence it overflows to the receiving-tank E. The forward ends of the pipes or tubes 1) may be entirely covered, or their extent of opening regulated, so as to regulate the passage of milk therethrough by a slide, O, working vertically upon the face of the front end of the vessel D represents the water-cooler for snpplyin g the vessel A with cold water for cooling the milk, as hereinafter described. This watercooling vessel D is provided with a central cell or compartment, (1, for the reception of a mixture of ice and salt or other suitable refrigerant. On either side of this compartment are tubes or passages g h, and at the forward end are two compartments, ef, the compartment 0 serving to receive the water that has lost a major part of its ehillby being used to cool the milk, and is returned to the water-cooler for refrigeration, and the compartmentf serving to convey to a suitable pipe for conveyance to the milk-cooler of recooled water. The pipe or passage 9 connects with the used-water compartment e, and conveys the water across the surface of the refrigerant-chamber d and discharges it into a chamber, 0?, at the rear of the vessel D, from whence it passes 'to the passage or pipe h to the compartment-f at the front, for

reconveyauce to the milk-cooler. Connecting with this latter chamber, f, and extending upward to the milk-cooling vessel A, is a pipe or tube, t, of rubber or other suitable material, which, by any of the well-known means-such, for instance, as a force-pump-supplies said vessel A with cold water, which surrounds the pipes b and chills the milk therein.

To the bottom of the vessel A is connected a return tube or pipe, 75, which conveys the water from said vessel back to the water-cooler D for refrigeration. This pipe is, fora portion of its length, passes through the milk-receivin g tank, and is provided at that portion with internal flanges, Z, by means of which the water will on its passage therethrough be forced against the sides of said pipe and impart to the milk in said tank the cold contained in said water. This pipe is provided with a valve, Z, which opens toward the water-cooler, and, permitting water from the milk-tank E, prevents any current passing from the water-cooler. A cut-off, m, arranged in said pipe k between the milkcooler and the milk-tank, enables the supply of return-water to said pipe to be cut off whenever desired. Another pipe, 0, extends from the bottom of the milk-cooler to the rearward portion of the pipe 70 and behind the valve 1, so that should it be at any time desired to return the used water to the water-cooler from the milk-cooler without its passing through the whole length of the pipe k, such may readily be done by simply closing the cut-off min pipe is and opening the cut-oft p in said pipe 0. When, however, the water is to pass through the passage therethrough of the pipe k, the cut-oft'p in pipe 0 is closed and the cut-0E m in pipe It opened.

The vessel A is open at its upper rear end, where a trough, A, is formed, into which the milk to be cooled is poured. The raised ends of the pipes I) pass through the rear wall of vessel A, their mouths opening into the side of the trough near its bottom, so as to receive and convey through said vessel any milk poured in said trough. The milk during its passage through the pipes b is cooled by means of the cold water supplied to the interior of the vessel through pipe 1 said water being first thoroughly cooled by coming in contact with the refrigerating-chamber of the cooler D, then caused to flow through pipe 1' into contact with the pipes b, to which its cold is imparted. It then returns through the pipe 70 to the watercooler 1), where, by its flow through the pipe 9, it becomes recooled and read y forretransinission to and reuse in the vessel A. When the milk has traversed the pipes b it drops down into the extended front end, a, of the vessel A, from whence it flows through orifice d to the spout 0, from which it flows into the tank E. The front ends of the pipes 11 may be wholly or partially closed, as it may be desired to regulate the flow therethrough of the milk by a vertically-moving slide, 0. The flow of water through the pipes can be easily regulated and the direction of its current changed at will by means of the cut-offs m and p, as heretofore explained.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

The combination of the milk-cooling vessel 'A, milk-tank E, the water-cooler D, having central refrigerant-compartment, (1, compartments cf at one end, and the tubes or passages g It on either side of said compartment d, and connecting with the compartments cf, for circulating the water through said watercooler, and the pipe 1', connecting with. compartment f, to convey cold water to the milkcooler A, the water-return pipe k, having internal flanges, l, cutoff m, and valve l, and passing through the milk-tank E, and the return-pipe 0, having cut-ofi'p, as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

EMANUEL KITCHEN.
